Question

See more:

I have a VB6 program which reads from a data acquisition systems and displays it on excel sheets. I added a sub module to do some 3-4 more calculations from the values already displayed above on the sheet.
My problem is even for simple calculations like see line for EBW, EIBA.. my manual calculations and the ones done my VB have an error.
What am I missing?

code goes like

VB

Public Sub ISO13256ACOIL() 'A-Coil Option
On Error Resume Next
If TestType = 1 Then 'Cooling Test
    EBW = ((IDLvgStandAirflow * ESP) * 0.3918) 'Eqv. Blower Watts
    EIBA = EBW * 3.413 'Eqv. Indoor BTU Adjustment
    AIC = NetIDCapacity - EIBA 'Adjusted Indoor Capacity
    ETW = CompWatts + EBW + PumpPenalty 'Eqv.Total Watts
    AIAC = (AIC + ISOAvg) / 2 'Adjusted ISO Avg. Capacity
    EPPA = AIAC / ETW 'EER with Pump Penalty
    frmISO.txtEIBA.Text = Format(EIBA, "#.##") 'send results to form ISO
    frmISO.txtAIC.Text = Format(AIC, "#.##") 'send results to form ISO
    frmISO.txtEBW.Text = Format(EBW, "#.##") 'send results to form ISO
    frmISO.txtETW.Text = Format(ETW, "#.##") 'send results to form ISO
    frmISO.txtEPPA.Text = Format(EPPA, "#.##") 'send results to form ISO
    frmISO.txtAIAC.Text = Format(AIAC, "#.##") 'send results to form ISO
End If
If TestType = 2 Then 'Heating Test
    EBW = ((IDLvgStandAirflow * ESP) * 0.3918) 'Eqv. Blower Watts
    EIBA = EBW * 3.413 'Eqv. Indoor BTU Adjustment
    AIC = NetIDCapacity + EIBA 'Adjusted Indoor Capacity
    ETW = CompWatts + EBW + PumpPenalty 'Eqv.Total Watts
    AIAC = (AIC + ISOAvg) / 2 'Adjusted ISO Avg. Capacity
    EPPA = ((AIAC / ETW) / 3.413) 'COP with Pump Penalty
    frmISO.txtEIBA.Text = Format(EIBA, "#.##") 'send results to form ISO
    frmISO.txtAIC.Text = Format(AIC, "#.##") 'send results to form ISO
    frmISO.txtEBW.Text = Format(EBW, "#.##") 'send results to form ISO
    frmISO.txtETW.Text = Format(ETW, "#.##") 'send results to form ISO
    frmISO.txtEPPA.Text = Format(EPPA, "#.##") 'send results to form ISO
    frmISO.txtAIAC.Text = Format(AIAC, "#.##") 'send results to form ISO
End If
End Sub

Solution 2

There is not solution, this code is not complete, this routine use variables that are not in the listing.

So the only advice is to run this code with debugger and the variables when you have the error.

It would help if you give us the error message.

Solution 1

Please pay attention to you variable data type.
Usually, variables EBW, EIBA.. should be define as Double type
